We consider the problem of designing waveforms for mitigating single tone jamming (STJ)
signals with an estimated jamming frequency in time-hopping spread spectrum (TH SS) …

The bit error rate performance of Rake reception of impulse radio ultra-wide bandwidth
signals over the IEEE 802.15. 3a channel models is evaluated. Instead of using Gaussian …

Multiaccess interference (MAI)-plus-noise whitening for detecting impulse radio ultra-wide
bandwidth (IR-UWB) signals transmitted over ideal free-space and the IEEE 802.15. 3a …

This study investigates the spectrum shaping observed in ultra-wideband (UWB)
communications. An auxiliary independent signal (AIS) to limit undesired spectral lines …

Offering a large bandwidth under strict transmission power limits, UWB communications can
overcome the spectral congestion and consequent performance impairment experienced by …

This paper deals with spectral shaping problem in impulse radio ultra-wideband systems
based on coded auxiliary independent signaling (AIS), as a modified version of transmitted …

Hopping Binary Phase-shift Keying (TH-BPSK) multiple access schemes for Ultra Wideband
(UWB) communications by validating an analytical study based on the bit error probability …

The paper proposes the chaotic time-hopping with pulse amplitude index modulation (CTH-
PAIM) system for improving anti-jamming performance and spectral efficiency. The proposed …

In this thesis, we analyze the performance of multiband OFDM UWB system considering
dual carrier modulation (DCM) constellations under frequency selective Nakagamim fading …

The unlicensed use of the ultra wideband (UWB) spectrum has been allowed in May 2002
by the US federal communications commission (FCC)[1]. A signal is considered as UWB if its …
